As a 3rd Line Engineer, you provide senior technical capability across complex incidents, planned change, and project delivery. This role focuses on design quality, technical risk management, and delivery of high‑impact work — ensuring solutions are robust, supportable, and aligned to agreed standards. You do not act as a permanent escalation queue or default owner of reactive tickets. Instead, you apply specialist expertise where risk, complexity, or impact requires senior technical judgement.

You report to the Technical Delivery Manager and work closely with engineering, service leadership, and solution design functions to ensure technical delivery is safe, predictable, and scalable. Our Service Operating Model (SOM) is established and approved by leadership and is actively being embedded across the organisation. This role contributes to strengthening that model in practice — reinforcing standards, improving design quality, and reducing repeat failure.
